Guys, got to go to have few beers tonight with my friends, but - that
kinda sucks ;-) I can guarantee you, that most novices, like me, will
swear like mad when developing and touching first recursion. I think,
that rebol's aproach of implicit global nature of words, even those
inside functions, is the main hell for novices :-)
One quick question - how is that with function recursion? Can I have
local
function value to one level of recursion call? And then shared
one? I know I can build my own stack, but ... :-) And if it is possible
with functions, parser should explicitly behave like that, even if it
breaks rebol rules :-) Will try with recursive function or stack later ...
